The powder was calcined at 620 C and then formed into a billet without binder, isostatically pressed, and then hot-pressed in an alumina die for 30 minutes at 1350 C with an applied stress of 28 MPa. Structure: The structure of fluorite was determined by Bragg (1914). Additional pattern: See ICSD 28753, 28785 and 29046 (PDF 01-075-0120, 01-075-0151 and 01-075-0390). To replace 00-004-0593.
